ARBOK MedZWD (Medical Zero Waste Discharge)

Overview

ARBOK MedZWD is a vacuum-based phase separation technology designed to fully eliminate liquid medical waste streams by converting them into clean water and dry, controlled by-products. Instead of filtering or chemically treating contaminated water, the system removes the water phase itself, leaving all contaminants behind. This approach eliminates biological activity, removes hazardous compounds from circulation, and stops secondary contamination. Compared to membrane and chemical systems, ARBOK closes the process completely and converts waste into stable outputs and usable resources. The solution is relevant due to increasing regulatory pressure, rising disposal costs, and the need for closed-loop infrastructure.

Applications

Primary use cases:

• Treatment of liquid medical waste (hospitals, clinics, laboratories)

• Hazardous wastewater streams with biological and chemical contamination

• Pharmaceutical and biotech effluents

Typical scenarios:

• On-site elimination of waste transport and disposal

• Replacement of chemical and thermal treatment systems

• Closed-loop water recovery systems

Industries and users:

• Hospitals and healthcare networks

• Diagnostic laboratories

• Pharmaceutical manufacturing

• Industrial hazardous waste operators

Scale:

• Small systems: 1–5 m³/day (labs)

• Medium systems: 5–100 m³/day (clinics, hospitals)

• Large systems: 100–250+ m³/day (medical complexes, industrial sites)

Operating Principle

The system operates under deep vacuum conditions, causing water to evaporate at low temperatures. Only H₂O transitions into vapor, while all contaminants (biological, chemical, and solid) remain in the residual phase. The vapor is then condensed into clean water.

Key steps:

1. Feed intake of contaminated liquid

1. Vacuum-induced phase change

1. Separation of vapor and residue

1. Condensation into clean water

1. Collection of concentrated residues

Limitations:

• Requires stable vacuum conditions

• Efficiency depends on feed composition and load balance

• Pre-screening may be needed for large solids
